IMPROVEMENT IN HARVESTERS Specification forming part of Letters PatentNo. 1 13,134, dated March 28, 1871.

- To all whom it may concern:

'Be it known .that I, J A0013 H. BEAM, of Springfield, in the county ofSan gamon, and in the State of Illinois, have invented a new and usefulImproved Grrain-Harvester;- .and do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawing, makin g a part'of this specification, in which--Figure. 1 is a top-plan view of my device; Fig. 2, an inside elevationof the principal traction and driving wheel and Fig. 3, a plan view ofthe fin ger-bar, shoe, and track-clearer for mowing.

Letters of like kind denote similar parts in each figure.

The nature of my invention relates to sidecutting two-wheeled harvesters.using pivoted shear-cutters, and capable of being converted readilyinto mowing-machines; and consists in the combination and arrangement ofits several parts, constructed as hereinafter described and set forth.

In the drawing, A represents the frame, rectangular in form, of greaterlength than width, with its outer side piece, B, projecting a little tothe rear of the inner side piece, G. This inner side piece hasprojecting below it three hangers, a, b, and c, of which I) is thecenter. To the hanger b a shaft is secured, upon which the main tractionand driving wheel D rotates upon the outside of the frame and close toit.

The wheel 1) has upon its inner face, near its edge, a circularcog-gear, D, the teeth of which mesh with pinions d and e, secured uponthe outer ends of the two main driving-shafts E and E, which extendhorizontally across the inner central face of said wheel. The shaft Erotates in the hangers a and b, and the shaft E in the hangers b and c.The shaft E has a crank, f, and the shaft E a crank, g, each near theinside of the frame A. This wheel has upon its face nearest the frame,and close to the edge thereof, a circular cog-gear, H, the teeth ofwhich mesh with the pinion I, rotating a shaft passing through a hanger,j, upon the underside of the side piece, B, in rear of the hanger i.

Upon the outside of the wheel G a grooved drum, J, is secured, a cord,k,around which, and around a drum, 1, upon the end of the reelshaft,gives motion to the reel.

Upon the outside of the standard j, and upon the outer end of the shaftturned by the pinion Lisa bevel-pinion, K, which meshes with anotherbevel-pinion, L, secured upon a shaft, M, running along by the side ofthe platformframe, and turning in proper brackets secured thereto. Theforward end of this shaft is hooked into one of a series of holes in alever, U, described hereinafter, by which its position may be adjusted,and it may be thrown into and out of gear at the will of the driver.This shaft has, also, near its forward end, a shackle, m, in order thatit may turn freely.

A standard, N, is attached to the outside of the side piece, B, by aset-screw or equivalent device, which standard rests above the frame Aand supports the reel-shaft O, which rotates within it, near its upperend.

The bottom of the reelstandard is provided on its inside with teeth,which fit into a corrugated toothed rack, a, properly secured to theoutside of the side piece, B. The reel-shaft is also supported inposition by a curved brace secured to the reel-standards, the ends ofwhich brace embrace said reel-shaft and allow it to turn within them. Tothis reel-shaft is attached any proper reel.

The platform P, made in any usual manner, is attached near its rear endto the main frame A by a slotted metallic strap, Q, provided with aset-screw, so that it may be ad justed vertically, and at its front endby a double-hinged strap, R, secured to the front under side of the mainframe.-

The platform-frame has upon its inner side a proper shield, 0, toprevent the grain from getting into the gears, and upon its outer side adivider, 19. Upon its outside it has also a carrying-wheel, S, turningupon a shaft se cured to a hanger, which is vertically adjusta ble byany proper means.

A curved brace, T, provided with numerous holes, is secured to the frontoutside end of the side piece, B, and the lower outside of the hanger t,with its curved portion bent downward. To some one of the holes in thisbrace the lever U is pivoted, which, rising up is bent inwardly, so asto be within convenient reach of the driver. I

To the lower part of the lever is attached the shaft M, beforedescribed, and to the upper part of it a rod, 19, adjustably connectedwith a cut-off, V, which moves back and forth over the platform.

Upon the top and front end of the side piece, B, a claw, g, is secured,into which a knotted rope, q-the lower end of which is attached to thestrap R--being placed, serves to regulate the vertical adjustment of thefront' of the platform P and the height of the cutting apparatus.

The shaft M, before described, has upon it two or more drums, 7",carrying rake-bands providedwith risers t, passing across and around theplatform, connected together by bars placed near each other, which barsare not shown in drawing, for the purpose of moving the grain when outand lyingupon the apron.

The pitrnan F is pivoted loosely upon the upper cutter-bar, W, and thepitman F, in the same way, upon the lower cutter-bar, one of which movesin one direction, while the other moves in the opposite direction.

The cutters X are in the shape of a spearhead, and are pivoted in theircenters upon the finger-bar u. The fronts of these cutters aresickle-edged, and so arranged that their sharp edges cross each otherwith a drawing cut. They may,if necessary, be provided with fingers o,and secured upon the rivets upon which the cutters are pivoted, and uponthe finger-bar, in any suitable manner.

When it is desired to use the machine for mowing, the platform, cuttingapparatus, reel,

have hereunto set my hand this 2d day of July, 1870.
